Cr12MoV电渣锭表面问题的工艺改进
首发时间:2019-11-05
摘要: Cr12MoV钢电渣重熔后钢锭表面渣沟严重,在锻造过程中易发生坯料断头情况。经过电渣重熔工艺改进,在不影响元素烧损和夹杂物评级的情况下调整渣系,提高冶炼初期输入炉内功率,缩短电流提升阶段和正常冶炼阶段的时间,有效解决了钢锭底端渣沟严重的问题。

Improvement of Surface Problem of Cr12 MoV Ingot
Abstract:After the Cr 12 MoV steel slag remelting, the surface slag groove of the steel ingot is serious, and the billet head is prone to occur during the forging process. After the electric slag remelting process is improved, the slag system is adjusted without affecting the elemental burn and inclusion rating, and the power in the furnace is increased at the initial stage of smelting, and the time in the current lifting phase and the normal smelting phase is shortened. The serious problem of slag groove at bottom of ingot is solved effectively.
